PIPEnl-IANGER.

SPECIFICATION forming part of Letters Patent No. 368,755, dated August 23, 1887.

Application filed December 16, 1886. Serial No. 221,808. (No model.)

To aZZ whom, it may concern:

Be itvknown that I, Riel-IARD T. CRANE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in PipeAHangers, which is fully set forth in the following specification, reference being had to the accompanying drawings,-

ject being to provide a hanger which may be placed in position upon the pipe at any point thereof when the pipe is in position or otherwise, thereby obviating the necessity of slipping t-he hanger over the end of the pipe and Ehen sliding it along upon the same into posiion.

To these ends my invention consists in certain novel features, which I will now proceed to describe, and will then particularly point out in the claims.

In the drawings, inwhich I have shown my invention practically carried out in one form, the pipe-hanger is composed of two sections, A and A', connected together by means of a hinge-joint. This hinge-joint may be of any approved form; but I prefer to employ the separable joint shown. In this construction one of the sections is provided with a cylindrical bar or pin, a, and is slotted immediately above said bar or pin, as shown at a', to receive a tongue or hook, a2, on the other section, which tongue or hook is curved to conform to the shape of the bar a, around which it passes when the parts are interlocked, as shown more particularly in Figs. 2 and 4 of the drawings. One of the sections of the hangenfor instance, the section A-is provided at its upper end with a circular boss, B, internally threaded, as shown at b, to receive the bolt which secures the hanger in position. For the outer half of the circumference this boss is reduced or cut away, and a half-boss, B', corrc sponding in size and form to the cut-away portion, is formed on the adj aeent end ofthe other section, A', so that when the parts are assembled the boss B and half-boss B will tit snugly the one upon the other, the whole forming a complete boss of equal diameter throughout. In order to cause the parts to interlock more firmly, a rabbet or shoulder, b', is formed upon the boss B, and a e'orre'spondiugly-shaped but reverse rabbet or shoulder, b2, is formed upon the half-boss B', the two interlocking, when united, in the manner shown in Fig. 2 of the drawings.

C represents a cap or nipple adapted to fit over the entire boss-that is to say, over the boss B and half-boss B when the two are united. A seat, c, is formed on the outer periphery of the boss to receive the said cap or nipple, the said seat extending around thecxterior of the half-boss B and around the uncovered half of the boss B, as shown. The cap or nipple C is hollow, in order to admit the securing-bolt,'and it is preferably reduced at its upper end to fit snugly around the said bolt.

The operation of my device is as follows: The two sections, being separated, may be placed in position around the pipe, either before or after uniting them, this placing in position being effected at any point desired. In case the hanger is applied vafter the sections have been interlocked by inserting the tongue or hook a2 through the slot a, or in case a nonseparable hinge-joint is employed, thescction will, while being applied, be swung open into the position shown in dotted lines in Fig. 2 of the drawings, in order to pass around the pipe. Vhen in position, the upper ends of the sections are brought together and the cap C placed upon the boss, thus securing the whole together. The securing-bolt is then passed down through the cap and screwed into the threaded aperture b, thus securing the hanger to the joist, beam, door, or other object from which it is to be suspended. The bolt will draw the upper end of the cap against the surface of the part to which the hanger is attached, :and will thus serve to hold the cap securely in position on its seat and prevent separation `of the sections.

It is obvious that various modifications in the details of construction may be made with- IOC out departing from the principle of my invention, and I therefore do not Wish to be understood as limiting myself strictly to the precise details hereinbefore described, and shown in the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a pipe-hanger, the combination, with the section A, provided with bar or pin a and slot d', of the section A', provided with the corresponding tongue or hook a2, substantially as and for the purposes specified.

2. In a pipe-hanger, the combination, with the two sections connected by a separable hinge-joint, one of said sections being provided with a boss to receive the securingbolt and the other section being provided With a partial boss to t thereon, of a cap or nipple to t over the two bosses and secure the two sections, substantially as and for the purpose specified.

tial boss B at the other end, and the cap or p nipple C, adapted to fit over the boss and partial boss to secure the Whole, substantially as and for the purpose specied.

4. In a pipe-hanger, the combination, with the section A, having bossB, reduced as described, of the sectionv A', having half-.boss B to t thereon,said boss and half-boss having i11- terloeking rabbets or shoulders b and b2, substantially as and for the purposes specified.
